Abstract: The field experiment was conducted at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture & Technology in Kumarganj, Ayodhya (U.P.) during the course of two consecutive Rabi seasons in 2021–22 and 2022–23. The treatment combinations of 4 crop residue management, viz. conventional tillage without residue, conventional tillage with residue (3 t/ha rice residue), zero tillage without residue, zero tillage with residue (3 t/ha rice residue) and 5 weed management practices, viz. Triallate 50% EC @ 1250 gm a.i. ha^-1, Triallate 50% EC @ 2500 gm a.i. ha^-1, Clodinafop propargyl 15% + Metsulfuron methyl 1% (60 gm + 4 gm a.i. ha^-1), hand weeding at 20 and 40 DAS and weedy check in wheat were tested with 3 replications in split-plot design, keeping crop residue management in main plots and weed management practices in subplots. Out of the various crop residue management techniques, wheat crop growth characteristics were significantly impacted by zero tillage with residue in both years, and then by conventional tillage with residue. While that in case of weed management practices, hand weeding at 20 and 40 DAS had significant influence on crop growth parameters of wheat during both the years closely followed by Clodinafop Propargyl 15% + Metsulfuron Methyl 1% WP PoE (60 gm + 4 gm a.i. /ha).
